操作中发生带负荷拉、合隔离开关应该（）。A、带负荷合隔离开关时，即使发现合错，也不准

Have you ever noticed advertisements which say “Learn a foreign language in 6 weeks or your money back”?
Of course, it never happens quite like that. The only language which is easy to learn is the native tongue. Before the Second World War people usually learnt a foreign language in order to read the literature of the nation. Now speaking a foreign language is what most people want. Every year millions of people start learning one. How can they do it?
Some people try at home, with books or tapes; some use radio or television programs. If they use the language only 2 or 3 times a week, learning it will take a long time. A few people have to learn a language fast by studying for 6 or more hours a day. It is easier to learn a language in the country where it is spoken in everyday life. However, most people cannot afford this, and for many it is not nesessary. They need the language in order to do their work better. For example, scientists chiefly need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and books will help. But they cannot do the students’ work for them.
